How can we improve Adobe Audition?

Please make it possible to scroll using the magic trackpad while holding a Wacom pen over the tablet.

At the moment the trackpad can be used to scroll (very effectively and smoothly). But when I use the Wacom pen simultaneously (as it makes cutting a LOT faster) the refresh rate of the Audition interface slows down by a factor of 1000 or so. Would be so glad if you made that possible.
